Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

The embodiment of the utility model provides a window air conditioner, which aims to solve the problems that an outer box and a chassis of the existing window air conditioner are inconvenient to assemble and disassemble and are prone to being connected with each other and are unstable, and the window air conditioner is described below with reference to the accompanying drawings.

In the embodiment of the present utility model, as shown in fig. 1, the window air conditioner 100 includes a base pan 10 and an outer case 20, the base pan 10 having a first connection side wall 11, the outer case 20 having a second connection side wall 21, specifically, in the embodiment, the base pan 10 has an outline of a box-like structure having an open top, and the base pan 10 has two first connection side walls 11 opposed to each other at intervals in a width direction thereof; the outer case 20 includes a top wall 22 and two second connection side walls 21, and the two second connection side walls 21 are respectively connected to the left and right sides of the top wall 22. When assembled, the outer box 20 covers the chassis 10, the chassis 10 is positioned between the two second connecting side walls 21, and the two first connecting side walls 11 on the chassis 10 and the two second connecting side walls 21 on the outer box 20 are arranged oppositely one by one.

In order to realize the connection between the chassis 10 and the outer box 20, the window air conditioner 100 of the present utility model further includes a connection assembly 30, as shown in fig. 2, the connection assembly 30 includes a connection rod 31, one of the first connection sidewall 11 and the second connection sidewall 21 is mounted with the connection rod 31, the other is penetrated with a connection hole 40, and the connection rod 31 penetrates the connection hole 40. Specifically, the connecting rod 31 may be fixed on the first connecting sidewall 11 of the chassis 10, or may be fixed on the second connecting sidewall 21 of the outer box 20, for example, in an embodiment, as shown in fig. 2, the connecting rod 31 is fixed on the second connecting sidewall 21 of the outer box 20, the first connecting sidewall 11 of the chassis 10 is correspondingly provided with a connecting hole 40, and the shape and size of the connecting hole 40 may be designed to fit with the connecting rod 31, so that the outer box 20 carries the connecting rod 31 to correspondingly pass through the connecting hole 40 during assembly.

It should be noted that, because the two second connecting side walls 21 are both provided with the connecting rods 31, the distance between the two connecting rods 31 is smaller than the distance between the two first connecting side walls 11, so in order to ensure that the connecting rods 31 can penetrate into the connecting holes 40, the second connecting side walls 21 of the outer case 20 can be deformed to a certain extent during assembly, the distance between the two corresponding connecting rods 31 is larger than the width of the chassis 10, and then the connecting rods 31 can be correspondingly positioned in the connecting holes 40 and penetrate into the connecting holes 40. Alternatively, the first connecting sidewall 11 and the second connecting sidewall 21 may be respectively provided with connecting surfaces extending horizontally and facing up and down, and the connecting rod 31 and the connecting hole 40 are respectively provided on the horizontal connecting surfaces, so that the outer case 20 may be covered on the chassis 10 from top to bottom during assembly, and the connecting rod 31 may pass through the connecting hole 40 without any deformation.

It will be appreciated that when the connecting rod 31 passes through the connecting hole 40, the connecting hole 40 can limit the movement of the connecting rod 31 in the radial direction thereof, that is, limit the relative displacement of the outer case 20 and the chassis 10 in the radial direction of the connecting rod 31, and at this time, the connection of the chassis 10 and the outer case 20 can be completed by limiting the relative movement of the chassis 10 and the outer case 20 in the axial direction of the connecting rod 31. Therefore, in the present embodiment, the connecting assembly 30 further includes a limit post 32, the limit post 32 is movably mounted on the connecting rod 31, and referring to fig. 3 to 6, the limit post 32 has a locked state protruding relative to the outer peripheral surface of the connecting rod 31, and an unlocked state retracted and positioned inside the connecting rod 31; returning to fig. 2, when the limit post 32 is in the locked state, the first connecting sidewall 11 and the second connecting sidewall 21 are both located on the same side of the limit post 32.

It will be appreciated that, because the stopper post 32 has a locked state protruding relative to the outer circumferential surface of the connecting rod 31 and an unlocked state retracted and positioned inside the connecting rod 31, the stopper post 32 can be put in the unlocked state at the time of assembly, at this time, because the stopper post 32 is retracted and positioned inside the connecting rod 31, the stopper post 32 does not protrude from the outer circumferential surface of the connecting rod 31 and does not protrude from the outer circumferential surface of the connecting rod 31 at will, so that the connecting rod 31 can pass through the connecting hole 40 very smoothly and quickly, more time and effort can be saved than screwing a screw, and the screw slipping or warping can be avoided. After the connecting rod 31 passes through the connecting hole 40, the limiting post 32 is switched to the locking state, at this time, because the limiting post 32 protrudes out of the outer peripheral surface of the connecting rod 31, and the first connecting side wall 11 and the second connecting side wall 21 are both positioned on the same side of the limiting post 32, the limiting post 32 can limit the first side wall of the chassis 10 and the second side wall of the outer box 20 to separate from each other along the axial direction of the connecting rod 31, and the connecting hole 40 has limited the movement of the connecting rod 31 in the radial direction, so when the limiting post 32 is switched to the locking state, the chassis 10 and the outer box 20 are assembled, the assembling efficiency is higher, the screw slipping or warping condition is avoided, and the firm connection can be ensured.

And when dismantling, also only need to make spacing post 32 retract and fix a position in connecting rod 31, then make connecting rod 31 break away from connecting hole 40 can to at the in-process of dismantling, because spacing post 32 location is inside connecting rod 31 and can not bulge at will, consequently can make connecting rod 31 can be broken away from connecting hole 40 smoothly swiftly, more labour saving and time saving than screwing up the screw, improved the dismantlement efficiency.

It should be noted that, the manner of implementing the "the switching between the locking state and the unlocking state of the limit post 32" may be various, for example, referring to fig. 4 and 6, the connecting rod 31 may be provided with a mounting cavity 311 in the connecting rod 31, the outer peripheral surface of the connecting rod 31 is further provided with a telescopic through hole 312 that is communicated with the mounting cavity 311, the limit post 32 is mounted in the mounting cavity 311, at this time, the limit post 32 may implement the telescopic movement on the connecting rod 31 through the cooperation of the motor and the transmission member (such as a gear, a rack, a screw, etc.), and when the limit post 32 is retracted into the connecting rod 31, as long as the motor is not started, the limit post 32 will remain positioned inside the connecting rod 31 and not protrude at will.

Or, the limit post 32 can be stretched out and drawn back on the connecting rod 31 through the cooperation of the push-pull rod and the connecting rod 31, specifically, one end of the push-pull rod extends out of the connecting rod 31 and can be pushed and pulled by an assembler, the other end of the push-pull rod is connected with the limit post 32 through the connecting rod, and the connecting rod 31 converts the sliding of the push-pull rod into the stretching movement of the limit post 32 on the stretching through hole 312. Therefore, an assembler can switch the limit post 32 between the locking state and the unlocking state through the push-pull rod, and when the limit post 32 is pulled into the connecting rod 31, the limit post 32 can be kept in the connecting rod 31 without randomly extending out of the outer peripheral surface of the connecting rod 31 as long as the push-pull rod is not pushed.

Still alternatively, referring to fig. 3 to 6, the connection assembly 30 may further include a sliding rod 33 and a first elastic member 34; the sliding rod 33 is slidably mounted in the mounting cavity 311, and a sliding groove 331 is formed in the sliding rod 33, the sliding groove 331 extends parallel to the axial direction of the telescopic through hole 312 (i.e. when the sliding groove 331 is coaxially aligned with the telescopic through hole 312, the sliding groove 331 extends along the axial direction of the telescopic through hole 312), the first elastic member 34 is mounted in the sliding groove 331, and the first elastic member 34 extends along the length direction of the sliding groove 331. One end of the limiting post 32 is slidably mounted in the sliding groove 331 and abuts against the first elastic member 34, and the other end extends out of the outer peripheral surface of the sliding rod 33; the limiting post 32 moves along with the sliding rod 33, and when the limiting post 32 corresponds to the telescopic through hole 312, the limiting post 32 extends out of the connecting rod 31 through the telescopic through hole 312 to be in the locking state, when the limiting post 32 is dislocated from the telescopic through hole 312, the limiting post 32 is abutted to the inner wall of the mounting cavity 311 to be in the unlocking state, and at this time, because the limiting post 32 is dislocated from the telescopic through hole 312 and is abutted to the inside of the mounting cavity 311 under the action of the elastic force of the first elastic piece 34, the limiting post 32 can be kept as long as the sliding rod 33 does not slide towards the telescopic through hole 312 along with the limiting post 32.

For the present embodiment, when the limit post 32 needs to be switched to the locked state, the slide rod 33 can be moved to the telescopic through hole 312 with the limit post 32 by pushing the slide rod 33 until the limit post 32 corresponds to the telescopic through hole 312, and the limit post 32 can be pushed out of the telescopic through hole 312 under the elastic force of the first elastic member 34 because the inner wall of the mounting cavity 311 is not limiting the limit post 32, so as to protrude out of the outer peripheral surface of the connecting rod 31, that is, the locked state is switched. When the limit post 32 is required to be switched from the locking state to the unlocking state, the limit post 32 can be pressed back to the mounting cavity 311 of the connecting rod 31, and then the limit post 32 is pulled back through the sliding rod 33, so that the limit post 32 and the telescopic through hole 312 are misplaced.

Further, in an embodiment, as shown in fig. 3 to 6, the connection assembly 30 further includes a second elastic member 35, the second elastic member 35 is connected to the inner wall of the mounting cavity 311, and the second elastic member 35 extends along the sliding direction of the sliding rod 33, and one end of the sliding rod 33 in the sliding direction abuts against the first elastic member 34. Specifically, when the limit post 32 is in the locked state, the sliding rod 33 compresses the second elastic member 35, and the second elastic member 35 generates elastic force, at this time, since the limit post 32 passes through the telescopic through hole 312, the second elastic member 35 cannot push the sliding rod 33. When the limiting post 32 is pressed back into the mounting cavity 311, the second elastic member 35 can push the sliding rod 33 to slide, so that the limiting post 32 is automatically switched to a position dislocated with the telescopic through hole 312, and the sliding rod 33 can be limited to move towards the telescopic through hole 312 with the limiting post 32 under the condition that no external force pushes the sliding rod 33, so that the limiting post 32 is prevented from extending out of the outer peripheral surface of the connecting rod 31 at will.

Of course, besides the second elastic member 35 to automatically switch the position of the limiting post 32 to the position offset from the telescopic through hole 312, the principle that the magnets attract each other in opposite directions and repel each other in the same direction can be used to push the sliding rod 33, so that the position of the limiting post 32 can be automatically switched to the position offset from the telescopic through hole 312 under the action of magnetic force after being pressed back into the mounting cavity 311.

Further, in an embodiment, as shown in fig. 3 to 6, the connection assembly 30 further includes a pushing member 36, where the pushing member 36 is mounted on the connection rod 31 and located at an end of the sliding rod 33 away from the second elastic member 35; the pushing member 36 is made of an electroactive polymer material and is electrically connected to the electric control board of the window air conditioner 100, and one end of the sliding rod 33, which is far away from the second elastic member 35, abuts against the pushing member 36. Specifically, in the present embodiment, the pushing member 36 is in a curved sheet structure, and the pushing member 36 is made of an electroactive polymer material, so that the pushing member 36 can shrink and deform when energized, and recover when de-energized. Therefore, by electrically connecting the pushing member 36 with the electric control board and abutting against the end of the sliding rod 33 away from the second elastic member 35, when the limit post 32 needs to be switched to the locking state, the pushing member 36 can be electrified, the pushing member 36 contracts and deforms and pushes the sliding rod 33 to slide until the limit post 32 corresponds to the telescopic through hole 312 and is switched to the locking state; after the limiting post 32 is clamped into the telescopic through hole 312, the pushing member 36 can be powered off, and at this time, the pushing member 36 is restored and is separated from the contact with the sliding rod 33, and the sliding rod 33 is not pushed to slide by the second elastic member 35 because the limiting post 32 is clamped in the telescopic through hole 312.

It can be appreciated that, by making the pushing member 36 from an electroactive polymer material and electrically connected to the electric control board, the pushing member 36 not only has a simple and light structure, but also can control all the pushing members 36 through the electric control board, so that all the limiting posts 32 can be simultaneously controlled to switch to a locking state, and the assembly efficiency is higher compared with a mode of screwing screws one by one.

Optionally, in an embodiment, as shown in fig. 3 to 6, two telescopic through holes 312 are provided on the connecting rod 31, and the two telescopic through holes 312 are coaxially opposite; the sliding groove 331 penetrates through the sliding rod 33, and two ends of the first elastic member 34 are respectively connected with the limiting post 32. When the sliding groove 331 is coaxially opposite to the two telescopic through holes 312, the two limiting posts 32 respectively pass through the telescopic through holes 312 and extend out of the outer peripheral surface of the connecting rod 31 under the elastic force of the first elastic member 34, so as to connect the outer case 20 and the chassis 10. It will be appreciated that such an arrangement not only enables the chassis 10 and the outer case 20 to be securely connected by the two limiting posts 32, but also simplifies the structure of the connecting assembly 30, and only requires one first elastic member 34 to push the two limiting posts 32.

Alternatively, in one embodiment, as shown in fig. 7, the connecting hole 40 is disposed on the first connecting sidewall 11, and the cross section of the connecting hole 40 is U-shaped and penetrates to the upper edge 111 of the first connecting sidewall 11; it can be appreciated that, by making the cross section of the connecting hole 40 be U-shaped and penetrate to the upper edge 111 on the first connecting sidewall 11, when the outer box 20 is assembled to the chassis 10 with the connecting rod 31, the outer box 20 only needs to make the connecting rod 31 correspond to the position right above the connecting hole 40, and then directly cover the chassis 10 from top to bottom, so that the second connecting sidewall 21 of the outer box 20 does not need to be deformed to a certain extent, further saving time and effort, and improving the disassembly efficiency. It will be further appreciated that, because the connecting hole 40 is U-shaped and penetrates to the upper edge 111 of the first connecting sidewall 11, in order to prevent the outer case 20 from moving upward relative to the chassis 10 and disengaging from the connection, in this embodiment, a limit stop 50 is further provided on the first connecting sidewall 11, and when the limit post 32 is in the locked state, the limit stop 50 is located above the limit post 32, and the limit stop 50 limits the upward movement of the limit post 32, and thus limits the upward movement of the connecting rod 31 and the outer case 20 relative to the chassis 10, so as to achieve the connection between the outer case 20 and the chassis 10. And because the limit stopper 50 does not interfere with the assembly and disassembly between the outer case 20 and the chassis 10 because the limit post 32 is retracted and positioned inside the connection rod 31 during the assembly or disassembly.

Alternatively, as shown in fig. 8, the connection hole 40 may be formed in the second connection sidewall 21, and the connection hole 40 may have a U-shaped cross section and penetrate to the lower edge 211 of the second connection sidewall 21; the second connecting side wall 21 is further provided with a limit stop 50, and when the limit post 32 is in the locked state, the limit stop 50 is located below the limit post 32. The connection between the outer case 20 and the chassis 10 is also facilitated, the assembly efficiency is improved, and specific principles are described with reference to the foregoing, and will not be repeated here.

The size, shape, etc. of the limit stop 50 may be flexibly designed as needed, and the limit stop 50 may be located directly above or below the limit post 32 or may be located obliquely above or below the limit post. In the case that the limit stop 50 is located at one side of the limit post 32 and the limit post 32 is required to be pressed and switched to the unlocked state, the limit stop 50 may affect the worker to press the limit post 32, so in an embodiment, as shown in fig. 7 or 8, the limit stop 50 is in a strip shape and one end thereof is rotatably mounted at one side of the connection hole 40, and the limit stop 50 is configured to be capable of rotating toward the connection rod 31 and pressing the limit post 32 into the connection rod 31; when the limit post 32 is in the locked state, the limit stop 50 abuts against the limit post 32 and is configured not to rotate in a direction away from the limit post 32.

Specifically, as shown in fig. 7, taking an example in which the connection hole 40 is provided in the first connection sidewall 11 of the chassis 10, the limit stopper 50 is elongated and its upper end is rotated at one side of the connection hole 40, and when the connection rod 31 is not mounted in the connection hole 40, the lower end of the limit stopper 50 is extended vertically downward. When the connecting rod 31 is installed in the connecting hole 40, and the limit post 32 on the connecting rod 31 extends out of the outer peripheral surface of the connecting rod 31, the limit stop 50 is pushed by the limit post 32 to rotate, and when the limit post 32 is completely extended out, the limit stop 50 just moves to a limit position, so that the limit stop cannot continue to rotate in a direction away from the limit post 32. When the lock is required to be detached, the worker can drive the limit stop 50 to rotate towards the connecting rod 31, and the limit stop 50 can press the limit post 32 in the rotating process, so that the limit post 32 is switched to an unlocking state. That is, in the present embodiment, by allowing the limit stop 50 to rotate and to press the limit post 32, the limit stop 50 can be used as a tool for a worker to press the limit post 32 while restricting the upward movement of the connecting rod 31 and the outer box 20, solving the problem that the limit stop 50 may interfere with the worker to press the limit post 32.

Alternatively, as shown in fig. 8, when the connection hole 40 is provided in the second connection sidewall 21 of the outer case 20 and the connection rod 31 is fixed to the first connection sidewall 11 of the chassis 10, the limit stop 50 is long and its lower end is rotatably mounted at one side of the connection hole 40, and when the connection rod 31 is not yet mounted in the connection hole 40, the upper end of the limit stop 50 is inclined and extended upward and in a direction away from the connection hole 40, and at this time, the limit stop 50 is just at a limit position, and the upper end of the limit stop 50 cannot continue to rotate downward. When the connecting rod 31 is fitted into the connecting hole 40 and the limit post 32 is switched to the locked state, the end of the limit post 32 just abuts against the limit stopper 50. When the lock is required to be detached, the worker can drive the limit stop 50 to rotate towards the connecting rod 31, and the limit stop 50 can press the limit post 32 in the rotating process, so that the limit post 32 is switched to an unlocking state. It will be appreciated that this also allows the bump stop 50 to be used as a tool for a worker to press the bump stop 32 while limiting the upward movement of the connecting rod 31 and the outer case 20, solving the problem that the bump stop 50 may interfere with the worker pressing the bump stop 32.

It should be noted that, when the limit post 32 is in the locked state, the limit stop 50 may be abutted to the limit post 32 and not rotatable in a direction away from the limit post 32, for example, alternatively, in an embodiment, as shown in fig. 7 or fig. 8, an anti-rotation stop 60 is further disposed on the first connection side wall 11 or the second connection side wall 21, and the anti-rotation stop 60 is located on a side of the limit stop 50 away from the limit post 32; when the limit post 32 is in the locked state and abuts against the limit stop 50, the limit stop 50 abuts against the anti-rotation stop 60, that is, the limit stop 50 cannot continue to rotate in a direction away from the connecting rod 31 due to the limitation of the anti-rotation stop 60, so as to stably limit the connecting rod 31. For example, in another embodiment, the outer peripheral surface of the rotating shaft of the limit stop 50 may be convexly provided with a limit pin, and the limit pin moves in an arc-shaped channel, and when the limit pin abuts against the side surface of the arc-shaped channel, the limit stop 50 may be limited to rotate in a direction away from the connecting rod 31.

Alternatively, in an embodiment, as shown in fig. 7 or 8, a pressing protrusion 51 is disposed on a side of the limit stop 50 facing the limit post 32, and the pressing protrusion 51 is used for pressing the limit post 32 back into the connecting rod 31. It will be appreciated that, because the limit post 32 extends out of the outer peripheral surface of the connecting rod 31 through the telescopic through hole 312, the telescopic through hole 312 has a certain thickness, and the end of the limit post 32 may be blocked in the telescopic through hole 312, so by providing the pressing projection 51, the pressing projection 51 may be smaller than the telescopic through hole 312, so that the limit post 32 is ensured to be completely pressed into the mounting cavity 311 of the connecting rod 31, and the situation that the end of the limit post 32 is blocked in the telescopic through hole 312 and is not switched to the unlocking state is avoided.

The size, shape, etc. of the pressing projection 51 may be flexibly set as needed, as long as the limit post 32 can be completely pressed into the mounter. For example, in an embodiment, as shown in fig. 7 or fig. 8, the pressing protrusion 51 has a hemispherical structure, and the hemispherical structure has a certain guiding function, so that the pressing protrusion 51 is prevented from being inadvertently blocked in the telescopic through hole 312.
